Isolation and identification of Pseudomonas fluorescens from the soil of Dulbergia sisso

Pseudomonas fluorescens (PGPR) beneficial bacteria that settle the plant roots and improve the plant growth by an extensive variety of mechanisms. The use of PGPR gradually increasing in agriculture microbiology and offers an attractive way to replace chemical fertilizers and pesticides. In this study, an attempt was made to collect rhizospheric soil sample isolation and record of native Pseudomonas population from rhizospheric sample and to identify the native Pseudomonas fluorescens strains, an intoxicating bio control agent as well as PGPR in the rhizosphere under UV light and further characterize them morphologically and culturally. Maximum P. fluorescence strains showed positive PGPR activity. The study showed that Pseudomonas as an effective plant growth promoting bacterium.
